Most of the dependencies are open-source will be downloaded automatically.
Most of the dependencies are open-source can be downloaded automatically by
going into the `install` directory and running `make`. It will first download
into the `install/Downloads` directory everything that needs to be installed.
The building of the dependencies takes place in the `install/_build`
directory, and the packages that are being installed can be followed by looking
at the log files in this directory. When a package was successfully installed,
a `*.ok` file is created and the log file is deleted.
If you don't have an internet connection available, you can execute the
downloading step on another computer and transfer all the downloaded files
into the `Downloads` directory.
The Fortran and C++ compilers, Python and Bash interpreters and the Lapack
library need to be installed manually by the user.
Installation
------------
The ``make.config`` file contains compiler specific parameters. You should change
them to match your hardware. You can copy the ``make.config.ifort`` or
``make.config.gfortran`` as a starting point.
The ``configure.sh`` script will first download the dependencies by running
``make`` in the ``install/`` directory. The configuration script will work in

Before using or compiling QMC=Chem, environment variables need to be loaded. The
environment variables are located in the ``qmcchemrc`` file:

The ``QMCCHEM_NIC`` environment variable should be set to the proper network interface,
usually ``ib0`` on HPC machines.
